EPA GHG Inventory shows US GHG down 1.7% y-o-y in 2019, down 13% from 2005

Green Car Congress

The US Environmental Protection Agency (EPA) released its 28 th annual Inventory of US Greenhouse Gas Emissions and Sinks (GHG Inventory), which presents a national-level overview of annual greenhouse gas emissions from 1990 to 2019. The number of vehicle miles traveled (VMT) by light-duty vehicles (i.e., from 2018 to 2019.

Proposed process for low-emissions coal-to-liquids

Green Car Congress

The EMS (Earth and Mineral Science) Energy Institute at Penn State has developed a conceptual novel process configuration for producing clean middle-distillate fuels from coal with some algal input with minimal emissions. Principal inputs are coal, water, non-carbon electricity, and make-up solvent. Background.

EIA: light duty vehicle energy consumption to drop 25% by 2040; increased oil production, vehicle efficiency reduce US oil and liquid imports

Green Car Congress

Energy consumption by light-duty vehicles in the United States, AEO2013 and AEO2014, 1995-2040 (quadrillion Btu). LDV energy consumption declines in AEO2014 Reference case from 16.0 quadrillion Btu in 2012 to 12.1 quadrillion Btu in 2040, compared with 13.0 quadrillion Btu in 2040 in the AEO2013 Reference case.

SGH2 building largest green hydrogen production facility in California; gasification of waste into H2

Green Car Congress

Energy company SGH2 is bringing the world’s biggest green hydrogen production facility to Lancaster, California. SGH2’s gasification process uses a plasma-enhanced thermal catalytic conversion process optimized with oxygen-enriched gas. It can also provide lowest-cost long-term storage for electrical grids relying on renewable energy.

Rice study finds using natural gas for electricity and heating, not transportation, more effective in reducing GHGs

Green Car Congress

Rice University researchers have determined a more effective way to use natural gas to reduce climate-warming emissions would be in the replacement of existing coal-fired power plants and fuel-oil furnaces rather than burning it in cars and buses.

Liquid Light unveils cost-advantaged catalytic process to make chemicals from CO2

Green Car Congress

Liquid Light unveiled its new process for the production of major chemicals from carbon dioxide, showcasing its demonstration-scale “reaction cell” and confirming the potential for cost-advantaged process economics. Large savings in feedstock costs: Liquid Light’s process requires $125 or less of CO 2 to make a ton of MEG.

EIA projects US energy-related CO2 emissions to remain near current level through 2050; increased natural gas consumption

Green Car Congress

Petroleum emissions from other sectors have fallen in recent years as equipment and processes that use petroleum fuels have been replaced by those using other fuels, in particular, natural gas. Natural gas is the least carbon-intensive fossil fuel, and for decades natural gas made up the smallest portion of US energy-related CO 2 emissions.
